Preview Form Shows during Crystal Report Loading Process

Question

Hi,
I have a slight issue on the behaviour of my application of how the report is loaded to the user.
Within my application, I have a button that when pressed - shows the print preview form with the report displayed.
The issue I am having - is that in some scenarios - preview form is visible to the user - along with a black screen (presuming a large dataset is being called and rendered) and THEN the report will appear
Code - appears in sub-routine called RunReport
           'Set up the printer
            Call SetReportPrinter()
            'Log into the report
            Call LogonReport(mReportDocument, crConnectionInfo)
            'Apply Parameters to the report
            Call SetReportParameters()
            CRViewer1.ReportSource = mReportDocument
            Me.Show() ' where the form is presented to the user on screen
Is it possible for me to show the preview form to the user - with all results loaded and ready to be displayed - so there is no delay in presenting the results to the user.

This is a known issue, track number 5000005116. Last communication with R&D re. this issue was June 5th and they are still working on a resolution. Latest service packs appear to improve the behavior, but does not resolve the issue as such. Try SP 5 from here:

Another possible work-around may be to export the report to rpt file format programmatically behind the scene (e.g.; would not see this), then view this exported report. It should display quickly as the report will be processed and with saved data.
